Frequently Asked Questions
Q: What is the difference between GWK-LHM-LW and GWK-LHM-LW-N?
A: GWK-LHM-LW-N includes locking fasteners with prevailing torque feature, which prevents fasteners from loosening during operation. Standard GWK-LHM-LW uses conventional fasteners. Choose GWK-LHM-LW-N if your jack will operate on rough terrain, in vibration-intensive environments, or if you prefer fasteners that will not require re-torquing. Both fit BT LHM 230 jacks.
Q: What are prevailing torque lock nuts and why do I need them?
A: Prevailing torque lock nuts have an interference fit or plastic insert that resists loosening from vibration and repeated movement. In a manual pallet jack with locking fasteners, the wheel axle fasteners will not back off during operation or storage. This is especially important if your facility has rough floors, heavy use, or if the jack sits unused for long periods. Lock nuts must be torqued to specification and replaced if removed.
Q: Does GWK-LHM-LW-N fit BT L-2000-U and L-2300-U series jacks?
A: Yes. According to the specifications, GWK-LHM-LW-N is compatible with BT LHM 230, BT L-2000-U, and BT L-2300-U series. Verify your exact model and serial number on the jack nameplate. If your jack is a different BT model or manufacturer, cross-reference the part number to confirm compatibility.
Q: How much torque should I apply to the lock nuts on GWK-LHM-LW-N?
A: Torque specifications depend on the fastener size and material. Consult the BT LHM 230 service manual or installation guide for the exact torque value. Typical axle fasteners on manual pallet jacks are torqued to 15 to 30 foot-pounds. Do not over-torque, which can strip threads. Do not under-torque, which can cause fasteners to loosen. Use a calibrated torque wrench.
Q: Can I replace worn wheels from GWK-LHM-LW-N without replacing the lock nuts?
A: If the lock nuts show no damage or corrosion, you can reuse them, but this is not recommended. Lock nuts lose their holding ability each time they are removed and reinstalled. Best practice is to replace lock nuts every time you remove the wheel assembly. This ensures maximum vibration resistance and wheel safety. New lock nuts are inexpensive compared to downtime from wheel failure.
Q: Is GWK-LHM-LW-N suitable for outdoor or wet environments?
A: Yes. The heat-treated, zinc-plated axles and ultra-polyurethane 70D wheels resist corrosion and moisture. The locking fasteners prevent fastener loosening in wet conditions. GWK-LHM-LW-N is a good choice for jacks used outdoors, near loading docks, or in facilities with regular floor washdown. Rinse wheels with fresh water after exposure to salt or chemicals to extend wheel life.
